FIELD OF THE DISCLOSURE

The present disclosure relates generally to tableware and containers and, more particularly, to a no slip vessel.

BACKGROUND

Vessels including containers and other tableware items such as cups are widely available for many different uses. One class of vessel is a bowl or plate used to hold a variety of foodstuffs for eating. These vessels are often used to feed children and babies. Youngsters, while learning their table manners, often will grab or slap at the vessel holding their foodstuffs knocking the vessel to the ground and spilling the contents. A variety of different solutions have been proposed that in one way or another fix a container to its supporting surface restricting the ability of the child to spill the vessel contents. Various approaches are described in U.S. Pat. Nos. 8,025,169; 8,028,850,8,757,418; 9,814,332; 9,844,205 and 10,058,200. Other approaches are described in US Patent Publication Nos. 2002/0040906, 2006/0201952 and 2018/0368594. In these prior solutions, the vessel or container is generally fixed or held to the underlying surface in such a way that the vessel is released by lifting but not by lateral motion. This creates a problem with small children who may grab the vessel in such a way as to release the vessel and causing the contents to spill. A need has arisen for a container that can be easily locked into position and not disrupted by childish antics.
